Re: Metalworking

RG: You beat me to it. How about the best way to get square corners on aluminum angle? When I first started playing with steel (I designed and cut my kayak rack from a Weatherguard and added some additional square tube for up-rights, and then had a pro weld it up), I used my wood working miter saw with an abrasive blade and melted the plastic guards somewhat. Now I have a proper abrasive blade chop saw and various Makita 4" grinders (I burned out a 3.5"), but the abrasives don't cut aluminum for crap.

So Silver350, et al. what should a guy who has all the wood working tools in the world do to adapt them to cleanly cut aluminum (and also shape/grind it)?

You can go to a good welding supply. I use a 4" disc for my Makita grinder specially made for aluminum. It works great. It won't load up.
For cutting aluminum flats, angle. etc. I use my porta-band saw.

Re: Metalworking

You can cut aluminum with a circular saw with a general purpose blade. Table saw, radial arm....
Jig saw also works.

Abrasive cutting disks just make a mess but you can buy aluminum specific grinding disks.

Re: Metalworking

I like using my miter saw if all possible, but I remember using a fine toothed plywood (?) saw blade which I thought would work well on aluminum, but it just caked up. I will look for aluminum saw blades for both the chop, miter, circular and table saw as well as that aluminum grinding disk.

That Portaband saw has always scared me. FYI, one of the projects on weldingtipsandtricks.com is making a cool stand for the Portaband.

Thanks to both of you.

Re: Metalworking

There's always the reciprocating saw too, but for long straight cuts nothing beats the table saw if you don't have a shear.
